Review on 🏕️ Ultimate Protection for your RV Roof - Bio-Kleen M02409 Roof Cleaner & Protectant in 1 Gallon Size by Tony Suggs

I bought this to clean my TPO roof. I poured it into a pressure sprayer and sprayed sparingly on a wet spot, then worked it over with a stiff brush. It was very little effort. Then I took a damp sponge and wiped away the remaining dirt. The sponge must be rinsed several times in a bucket of clean water. The area was then hosed down, paying particular attention to the area where water might run down the fairing. It only took about a quarter gallon to do the entire roof on our 21 foot. Follower. In the picture you can see the difference in the small area where I started.
